lIMPROVl-ID PUNCH.

To ALL wHoM rr MAY eoNonnN:

Be it known that I, LORENZ WOLF, of St. Jacob, in the county of Madison,and State of Illinois, bave invented a new and useful Improvement inPunches and I do hereby declare thatthe following is a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is afront elevation of my improved fpuneh. v

Figure 2 is a horizontal section ofthe same, the line a.' x, fig. 1,indicating the plane of section.

Similar letters of reference indicate like parts.

The object of this invention is to provide a standard for guiding aslidingpunch in such a manner that the socket in the standard may beenlarged or diminished at pleasure, according to the diameter or size ofthe tool which isto slide therein. y

The invention consists in providing a groove in the face of a curvedstandard. rising from a bedplate, the latter being, by means of screwsor otherwise, secured to lsuitable supports. A groovedcap is screwed tothe face of the standard, and by the grooves in the said standard and inthe cap, a socket is formed which corresponds with the square orpolygonal shank of the punch that is to slide in the said socket.Between the lcap yand standard are provided India-rubber or othersprings, which, in connection .with the screws by which the cap is heldto the standard7 serve to allow the adjustment of the cap for larger orsmaller-sized Shanks.` The said Shanks need not be made as accuratelywhen to be used in this machine, as the latter is made so thatconsiderably different sizes of Shanks can he used therein, and,consequently, the manufacture' of the punches forithisV machine will beless expensive than for any other knowndevice for similar purposes. Inthe aforesaid bed-plate is provided a cavity for receiving dies ofdifferent sizes, to correspond to different punches, which maybe-insertcd in vtheir sockets so that holes of diierent sizes can bepunched `in iron or steel with ease and rapidity.

A represents a-punch, with a square or polygonalshank, a, which isfitted in a corresponding socket in the end of an arm or standard, B,rising from the bed-plate C. Half of this socket is formed in shape of agroove in the face of the said arm B, and the other half in a cap, D,which is fastened to the arm by means of screws b b, as shown. Betweenthe cap D and arm B are arranged India-rubber or other springs d d,which, when aV larger socket is required, serve to keep the cap rni,while it is, by means of the screws, set from the face of the arm B. Toget a more accurate guidance for the punch, the socket is hollowed outin the centre, only its upper and lower end coming in contact with theshank. The standard B is so curved that pieces of metal of various widthmay be admitted under the punch; and the socket, in its upper end, is ofsuicient length to guide the punch perfectly. The bed-plate C isprovided with a hole, e., large enough to let the burs of the largestpunch to be used pass freely. This hole terminates on top in a cavity,f, which is to receive the dies; and the latter are so arranged as to bereadily changed in accordance with the size of holes to be produced.

I claim as new, and desire to secure by Letters Yatent The grooved capD, curved and grooved standard' B, screws b, and springs d d, incombination with the punch and die, all as set forth.
